Ladder mesh welding machine
TNL  

TNL is a ladder mesh welding machine for the production of curved or straight electro-welded ladders from coil, mainly used in precast tunnel segments reinforcing.
Its advanced technology guarantees perfect straight and curved ladders for precast with the lowest tolerances.
The machine comes with a shear movable on 3-axes and a programmed feeding system, which allows to have different cross wire pitches within a single electro-welded element.

In combination with the mesh welding machine, TNL is the right solution for manufacturing tunnel segments.
